The Martian Chronicles is a science fiction fix-up novel written by Ray Bradbury in 1950.
The novel is written as a chronicle and each story is a chapter within an overall chronological ordering of the plot.
It was not specifically written to be a single since its creation as a novel was suggested by a publisher after most of the stories had already appeared.
The book treats the exploration and settlement of Mars by Americans leaving a troubled Earth which it will be devastated by a nuclear war.
